When the police arrived, they told the couple the bundle probably came from a small aircraft that smugglers use to deliver drugs from Mexico to Arizona and that it was part of a larger parcel and was dropped by mistake.

Nogales Police Chief Derek Arnson and Sheriff Antonio Estrada said that it is common for drug traffickers to use ultralight aircraft to smuggle two, three bundles without stopping, just dropping them off, but that they had never hit a residential building before.
